Mylanta Warnings

You should not take Mylanta if:

You are allergic to any of the ingredients in the medication

You've had a colostomy or ileostomy

You have a blockage in your stomach or intestines

You have a hole in your intestines

You have poorly functioning kidneys, kidney stones, or kidney failure

You are bleeding from the stomach

You are dehydrated or are restricting fluids

Do not take Mylanta within two hours of another drug, since Mylanta can interfere with absorption of other medications.

Pregnancy and Mylanta

Mylanta is a Food and Drug Administration (FDA) Pregnancy Category B drug, meaning animal studies indicate there is no risk to a fetus, but there are no human studies showing it's safe for an unborn baby.

If you are pregnant or plan to become pregnant, talk with your doctor before taking Mylanta and never take high doses or large amounts of it.

Since Mylanta passes into breast milk, talk to your doctor before taking it if you are breastfeeding or plan to breastfeed.
